x -This invention relates to cream separators 'provided .with-a ireelyy suspended drum of ythatV type in which the driving ofthe sus- Y pension rod is produced by a hollow shaft;

Y e -5 Asiswellknown, in cream vseparators of this type,the suspensionrod of the drum generallyfcooperateswith a guide the function l0f which is'nto limit the/oscillations of the rodr.-y In order to make this guideL as efficient :j 10 as possible, itis desirableto havethe guide L exert` its action on a rodof considerable length and at apoint on the rod as near as possible to vthe-drum. v This condition, however, is not met in the-known constructions, since, in order 1,5 to' facilitate dismountin'g of the `driving membersfand lto insure proper lubrication,y the f guide is generally combined with they ball bearing supporting the lower end of the hol- `low`shaft',which is provided with a worm or 'u A zoother driving'members.V c Moreover, in those constructions, the whole assembly comprising l rthemed, theguide, theball bearing and the v.hollowshaft must be removedfrom-the drivring'gear box of theseparator throughkthe Consequently, ad-

. apparatusy isimpossible:

" 4flhis inventionhas for 'its object to obviatey -these disadvantages and toprovide a `conl ,30 structionin which the hollow driving shaft for'thefsusp-ension rod of the drum is considerably reduced in length" as compared with v 'rior devices of this kind, whereby it is possij lefal'so toreduce the vdiameter of its bore and 35 at thev same time to .insure y'the Aproper" amplitudeofoscillation of the suspension rod." It hasalso `for its objectto render possible the use jof' a/guide which-'caribe adjusted from y "40 the outside of the apparatus andwhich does 1'not-'interferewiththe easy' dismounting of s the suspension rod. c. 7.

'9' Y wYith this object in view, the invention esrsentially 'consistsin the special arrangements g15and v combinations 'of parts hereinafter fully described andfpointedout iny the app-ended i Ingthe` annexed drawing I separator constructed according to the invention. f Fig 2 is an enlarged view of a detail of r`the mechanism. The frame comprises, as usual, a box or casing 2 in which are mounted f gearing 3, 4 and a Worm-wheel 5 for transmitv`ting motion toahollow shaft 6 by means of sa worm formed on the periphery of said shaft.-

Yrod 13 from'which thevdrum 14 is suspended.

This rod 13 is rotated by the hollow shaft',`

.in a known mann-er, for'instance by means of a clutch comprising a spring 141 encircling the upper end of the shaft and securedl atone end to one of a pair of nuts 15 threaded on the end of the rod'13. f 7.

Therod 13 passes freely through an opening 16 formed in a bracket or projection 17 extending from the-wall of the gear box, in

which bearingis secured a sleeve'lS. On this i sleeve 18 at opposite sides of the rod 13, spindles'19 are mounted on which pass the cables 2O of aguide which is adjustable from the outside by means of a screw 21. The bracket 17 and the sleeve 18are independent from the Vball-race Sand are placed at the'greatest possible distance from said race, in order to act on a length of rod as great as possible. Moreover the casing 2 is provided, in its lower part, with an opening 22 through which passes the rod 13 and which is normally covered by an inverted cup 23;

" The cup 23, instead of being permanently secured as heretofore on the rod 13, is in ythe present instance fixed on said rod by friction.` To this end, the rod 13 is provided with 9 a member 24 of ogee form exteriorly and havmg afange at its lowerl end, theportion imvmediatelyvabove the flange forming an annular groove for the reception of a rubber packing ring 25 secured in a groove 26 formed andsimplicity kin construction.- We claim:

opening ofthe packing ring 25, then'through' the opening in the plate of the guide-member,

and, after having been passed through the Vhollow shaft, 6, it is connected with the latter outside of the gear-box by means of the vspring 14 and nuts 15. In the meantime, the

upward pressure on the rod has caused the upper enlarged portion of the member 24 to' pass through the opening in the packingr ring 25, fso that the latter now enters the annular groove infsaid member and thus'secures'thecup 23 on the rod. lVhen the mech- '.anism `is vto'befdisassembled, it is necessary only Ito remove the drum 14 andthe nuts 15 and then exert a downward pressurey on the Prr'odj13. They cup 23 being then seated on the, lbottomwall of the gear box aroundthe opening 22, byexerting a downward thrust on the rod 13 the enlarged upper portion of vthe member :24e-can readilyv be caused to pass Athrough `the opening in the packingl ring, thus releasingthe Cup V23 from the rod and permittingthe latter to be removed through the opening 22`in the bottom of the gear case. a It will be observed, that in this construction, asfthe'rod 13 cannot be removed through Vtheupper part ofthe casing orjbox2 together `withthe cup 23, the.' guide 20 does notl interfere withfthe removal of the rod and that it is not necessary as heretoforetoremove si-l multaneouslyf'rom the driving box, the hol! l low shaft and its ball bearing. Those members may consequently have dimensions which are considerably reduced. ,Moreover, as 'the hollow shaft and its Aball bearing 8 4are' at a distance from the guidefthe length `,of the rod 13on which the said guide acts is greater than :in the usual constructions, so that avbetter guiding ofjtherod is obtained .together withl great facility of dismounting 1.
